如何删除Emacs中的当前行？ [英] How can I delete the current line in Emacs?

问题描述

与vi的 dd 相当的emacs是什么？我想删除当前行。尝试 CTRL + k ，但只会从当前位置删除。

解决方案

  Ca＃转到行首开始
 Ck＃当前点
  

还有

  CS-backspace＃Ctrl-Shift-Backspace 
  

它调用 Mx kill-whole-line 。

如果你想设置一个不同的全局键绑定，你可以把它放在〜/ .emacs中：

$ b $ （全局设置密钥\C-cd'kill-whole-line）＃将`Cc d`设置为'Mx kill-whole-line`

---

如果要删除多行全部，可以在命令前加一个数字：

  Cu 5 CS-backspace＃删除5行全部
 M-5 CS -backspace＃删除5条全行
 
 Cu CS-backspace＃删除4条全行。没有数字的铜默认为4 
 
 Cu -5 CS-backspace＃删除以前的5条全线
 M  -  5 CS-backspace＃删除以前的5条全线
  

有时我还会发现 Cx z 帮助：

  CS-backspace＃delete 1整行
 Cx z＃重复上次命令
z＃再次重复最后一个命令。 
＃按需要按z次数。 
＃任何其他键正常运行，并结束重复命令。 
  




What is the emacs equivalent of vi's dd? I want to delete the current line. Tried CTRL + k but it only deletes from current position.

解决方案

C-a # Go to beginning of line
C-k # Kill line from current point

There is also

C-S-backspace   # Ctrl-Shift-Backspace

which invokes M-x kill-whole-line.

If you'd like to set a different global key binding, you'd put this in ~/.emacs:

(global-set-key "\C-cd" 'kill-whole-line)     # Sets `C-c d` to `M-x kill-whole-line`

---

If you want to delete a number of whole lines, you can prefix the command with a number:

C-u 5 C-S-backspace    # deletes 5 whole lines
M-5 C-S-backspace      # deletes 5 whole lines

C-u C-S-backspace      # delete 4 whole lines. C-u without a number defaults to 4

C-u -5 C-S-backspace   # deletes previous 5 whole lines
M--5 C-S-backspace     # deletes previous 5 whole lines

Sometimes I also find C-x z helpful:

C-S-backspace         # delete 1 whole line
C-x z                 # repeat last command
z                     # repeat last command again. 
                      # Press z as many times as you wish. 
                      # Any other key acts normally, and ends the repeat command.
